No problem! Let me at least share the steps id take if i were in your situation. Id first check to make sure that the Automatic Headlights option (If equipped) is not selected. If it is, try toggling the headlights manually after replacing the ballast. The problem with using the Auto function for the headlights is that in some cases, like if you were to pass under an overpass, or through a tunnel, the car will tun on the headlights just for them to turn off within the minute. This constant On/Off cycle does not give the ballast and bulb enough time to warm up which can cause this issue (Yes, even if just one ballast is affected it happened to me with my fog lights when i was running HID's in them. Although, it was caused from me having to flash my high beams- which turns off the Fog's while they are on- in some situations). Think about it this way, its the same theory that tells us that warming up our cars before driving is better for the engine, because we're letting oil circulate to all the moving parts and lubricate them, than short trips in which the engine does not fully warm up and allow oil to touch every part of the engine. My rule of thumb (since my car is not equipped with automatic headlights) is to leave them on for the duration of my drive even if they are no longer needed. Hope this helps! it may sound stupid but i have tested this out on many of my friends cars and have seen positive results so its worth a shot at least!
